of the city of Spring'eld',Green county, State 1 of Missouri, have invented certain new and useful 'Improvements in Lock- Faucets of which the following is a full, clear, and exact specifically stated consists of a suitable cas,M

ing; a nut upon the outer end of the casing;

exterior screw-threads upon the periphery of l the casing just inside of the nut and adapted to screw into the bung-hole of the barrel; a iiange extending inwardly froInLthe inner end of the casing and-formingabearing; a tubui lar valve slidinglynlounted in'said bearing, the inner end of saidvalve being closed yand y there being openings through the wall of said valve near the inner-end;, a ,rubber vgasket mounted around the valve in the casing i against the inner face of said flange; a metal washer against the outer face of said gasket;

a ange extending outwardly from near the outer end of said valve andiitting closely inl the openingin said casing; a coil-spring connecting said metal washer with Said fiange; a disk upon the inner end of said valve, the expansive tension of said spring operating to hold said disk yieldingly against the inner face of the' first-mentioned iange; an arm projecting inwardly from the casing, each side of said arm forming a stop; lugs extend` ing from the periphery of ysaid disk, one on each Side of said stop; an outer inclined face extending laterally from the inner end of Said stop-arm to beengaged byone of Said lugs to press said disk against the casing and hold the faucet closed; an inner inclined face eX- tending laterally from said Stop-arm to be en',- gaged by said lug and hold the Valve'open a faucet adapted to be inserted into the Outer end of said casing; a pin extending inwardly from said faucet and adapted to engage in a locking-notch in the outer end of Said valve, so as Vto rotate the valvev when the faucet is rotated; a" gasket' against theouter face of the valve-liange inf positionto'be engaged by the inner end'of the faucetg' a cam-pin extending into the opening at the outer end of the casing; aycam uponthe periphery of said nfaucetin, position to engage'said cam-pin, so that the faucet cannot be withdrawn from the, casing except when the valve is in its closed position; a second cam upon the periphery'ot` said faucet in position to engage said cam-pin to hold the faucet in position in the casing while the valve is open, and a thimble loosely mounted in the outer end of said valve, so that when an attempt is made to open the valve without the use of the faucet the thimble will turn without opening the zvalve.

Figure l is a longitudinal sectional detail of the casing and the inner end of the faucet, the faucet being removed from the casing. Fig.v 2 isa view analogous to Fig. 1 with the faucet insertedin the casing. Fig. Sisa view A in elevation of the inner end of the casing. Figli isa view in elevation of the inner end ofthe faucet, the outer end of the faucet be- :ing broken away. Fig. 5 is an end elevation of the, inner' end of the faucet. Fig. 6 is a :top plauview of the inner end of the casing as shown-in Figs. l and 2, drawn to show a Stop-arm and inclined face locking the valve closed and locking the valve open.

Referring to the drawings in detail, the casing 7 has a nut 8 upon its outer end and screwthreads 9 upon its periphery immediately inside of the nut, Ysaid screwfthreads being adapted to screw'into Athe'b'unghole of the barrel 10 and said 'casing being adapted to extend inwardly Ifrom the wall of the barrel. A flange ll extends toward the'center from the inner end of the casing 7 and forms a bearing, in which the valve 12 is slidingly mounted. A soft-rubber gasket 13 is placed against the outer face ofthe ange 11 around the valve 12, and a metal washer 14 is placed against the outer face of the gasket. A peripheral ange 15 is formed near the outer end of the valve 12 and ts closely within the opening 16 of the casing, and a coil-spring 17 ,connects the iange 15 with the washer 141. A

disk'lllislixed upon the innerend of the Valve l2, and the expansive .tension ofthe coil-spring 17 is exerted to hold'thedisk 18 yieldingly against the inner face Vof theilange 11. A stop-arm 19 extends inwardly from the inner end of the casing; each side of said ICO arm serving as a stop, and the stop-lugs 2O and 21 extend peripherally from the disk 1S, one upon each side of said stop'arm. An inclined surface 22 extends laterally from the inner end of the stop-arm 19 to be engaged by the stop-lug 2O to force the disk 18 against the flange 11 and hold the faucet closed. An inclined surface 23 extends laterally from the stop-arm 19 to be engaged by the stop-lug 2 and hold the faucet open, as shown in Fig. 2. Openings 24 are formed through the wall of the valve 12 a short distance from the disk 1S, so that when the faucet is opened, as shown in Fig, 2, liquid may pass inwardly from the barrel through said openings 24 and outwardly through the faucet, and when the faucet is closed, as shown in Fig. 1, no liquid can pass through said openings 24.

A soft-rubber gasket 25 is placed against the outer face of the peripheral flange 15, and a locking notch or recess 2G is formed in the periphery and extreme outer end of the valve12.

A faucet 27 is adapted to have its inner end inserted into the opening 16 of the casing and has a locking-lug 2S to engage in the notch 26, as required to rotate the valve when the faucet is rotated. A cam 29 extends outwardly from near the inner end of the faucet, and a similar cam 30 is formed upon the periphery of the faucet some distance outside of the cam 29. A cam-pin 31 extends into the outer end of the opening 16 to engage the lugs 29 and 30.

The parts are so assembled that when the faucet 27 is inserted into the opening 16 the cam 29 will strike the pin 31, and then the faucet is rotated until the pin 31 or right-hand end of the'cam 29 is as shown in Fig. 4. Then by pushing the faucet inwardly the pin 28 will enter the notch 2G. Then the faucet is rotated in the opposite direction until the stop-lug 2l strikes the stop-arm 19. Then the faucet is pushed farther into the casing, then pushing the valve through the bearing in the flange 11 and carrying the stop-lug 2O past the ends of the inclined surfaces 22 and 23 and carrying the cam 30 past the pin 3l. Then the faucet is again rotated in the reverse direction. The cam engages the pin 31 and passes inside of said pin. The stop-lug 20 passes along the inclined surface 23 to the end 32 of the stop-arm 19. Then the regular valve of the faucet may be turned and the desired amount of liquid drawn. Then the faucet is removed from the casing, leaving the valve closed in the position shown in Fig. 1. The thimble 33 is loosely mounted in the outer end of the valve 12 and held in position by means of the pin 34 operating in the groove 35, so that when the faucet is out of the easing and an attempt is made to open the valve the thimble 33 will rotate in the valve and the valve will not be opened.

Torsional tension of the spring 17 is exerted to hold the valve in its position and resist any attempts at opening the valve without the use of the faucet.
